I grew up bowling in a 16-lane, family-run center in Berwyn, Illinois, and they had an old wooden ball on the shelf in the office. They're very cool to look at. As to worth, I would have no idea. I'm sure there can't be too many floating around out there, but then I'm not sure there's much of a market for them either. I found an old internet posting that stated a guy had seen some sell for as much as $200-400 back around 2007, but then he gave a link to an ebay auction that had it selling for under $100. I guess just like anything else, you're just going to have to see if you can stumble across the right buyer. Good luck.
